New Jersey public safety exams

By NJ Civil Service Navigator Editorial Team · Updated July 23, 2026

New Jersey hires police, correctional, parole, and firefighter candidates through Civil Service exams. Guides to each entry-level and promotional public safety exam.

New Jersey fills its sworn public safety titles through Civil Service examinations. Police, correctional, and parole officers are tested through the Law Enforcement Examination, while firefighters have their own open competitive exam with a separate set of residency and volunteer rules. Both paths run on eligibility lists, and both reward knowing the rules before you apply.
